复现python3的str.isascii()

def is_ascii(input_str):
    try:
        input_str.decode("ascii")
        return True
    except UnicodeDecodeError:
        return False
    
def mxd_path_check(mxd_path):
    if not is_ascii(mxd_path):
        return mxd_path.decode("utf-8")

    return mxd_path

使用json打印避免中文乱码

import json

# 字符串处理
res = "xxxx"
print(json.dumps(res, ensure_ascii=False))

# 文件处理
file = 'xx.json'
with open(file, 'r') as f:
    print(json.dumps(json.load(f), ensure_ascii=False))
